Australia’s tennis stars have extended their charmed run at the Miami Open with Jordan Thompson and Alexei Popyrin progressing on Thursday.

Thompson and Popyrin now join Wednesday’s winners Nick Kyrgios and Thanasi Kokkinakis in the second round.

Both players had to work hard for their victories.

World No.78 Thompson lost the opening set to experienced Frenchman Jo-Wifried Tsonga 7-6 (7-1) before bouncing back to win the next two 6-4 6-4.

He will now meet compatriot and No.25 seed Alex de Minaur, who received a bye, for a place in the last 32.

Popyrin also had his work cut out against Lorenzo Musetti before he triumphed 7-5 7-6 (7-5).

The world No.92 next takes on Marin Cilic.

Joining the Australian contingent in the round of 64 is former world No.1 Andy Murray.

The Briton and two-time Miami Open champion accounted for Argentinian Federico Delbonis 7-6 (7-4) 6-1, with his reward a next-round meeting with Daniil Medvedev.

Medvedev’s first stint at the top of the ATP rankings ended swiftly when he lost in the third round at the Indian Wells Masters and was displaced by Novak Djokovic.

But the Russian has the opportunity to leapfrog Djokovic once more by making the semi-finals in Miami.

Before thinking about the latter stages of the Masters 1000 tournament, however, Medvedev first must master Murray, who looked in good nick on his return to Miami.

“It’s a big challenge for me, a big test,” Murray said. “I’ve got a big training block after this tournament and it’ll be a really good test for where my game’s at and the things I need to work on as well against him. I’m looking forward to that.”

That is not the only mouthwatering second-round tie, with Kyrgios meeting Andrey Rublev.

However, Stefanos Tsitsipas has a slightly more straightforward task on paper after qualifier J.J. Wolf advanced past Daniel Altmaier.

Kokkinakis takes on Argentine Diego Schwartzman in his next match.
